METALLIC SEAL FOR LETTERS, 65e.

Specification of Letters Patent No. 25,842, dated October 18, 1859.

To all lwhom 'it may concern:

Be it known that I, CHARLES A. MoEvoY, of Richmond, in the county of Henrico and State of Virginia, have invented a new and useful Improvement in Metallic Seals for Letters, &c.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l, is a plan view of an envelop sealed with one of my seals. Fig. 2, is a longitudinal vert-ical section of the same with the seal ready to be closed. Fig. 3, is an inverted plan of an envelop sealed with my met-allic seal. Fig. 4:, is a vertical longitudinal section of an envelop with the seal closed, and Figs. 5 and 6, exhibit the two parts of the seal.

Similar letters of reference, in each of the several figs. indicate corresponding parts.

My invention consists in the use together, in the manner hereinafter described, of two metallic concave disks having sharp points projecting from their circumferences said points having an inclination toward the center of the disks.

To enable others, skilled .in the art, to make and use my invention, I will proceed to describe its construction and operation.

a, Z), represent the metallic disks; c, (Z, the points of the same. These disks with points are formed out of a flat piece of metal by means of a cutting and forming die which has a funnel shaped body and a semispherical top, after the manner shown in Fig. 5. However, any other method found best in practice for producing them may be adopted. To use these disks as a seal for a letter; the disk a, is placed under the back leaf of the envelop and its points forced through the same, and the disk b, is placed against the fly leaf or lap of the envelop opposite the disk a, and its points forced through Said lap, as shown in Fig. 2. Thus arranging the disks, brings the points c, against the concave of disk b, and the points d, against the concave of a. Now by applying force or pressure to the disk a, the two disks will come together, the points of the saine being bent inward by contact with the concave surfaces. Thus bringing the disks together and bending down the points, causes the letter to be perfectly sealed; as the points d, press against and hold down the fly or flap of the envelop, while the points c, press against and hold up the back leaf of the envelop against the fly or flap, as illustrated in Fig. Il.

What I claim as my invention and desire to secure by Letters Patent, is

The use together, in the manner herein described, of two metallic concave disks hav ing sharp points projecting from their circumferences, substantially as set forth.

The above specification of my impt. in metallic seals, signed by me this 26th day of September 1859.
